About Study Course

Objective

- to acquire knowledge of the principles of deontology; - to acquire knowledge of subjective and objective examination methods – survey, inspection, palpation, percussion, auscultation, and interpretation results; - to teach students learn to assess laboratory and instrumental data; - to provide students with the basics of writing a medical history; - to encourage students in clinical thinking and decision-making.
